Hi
Firstly i certainly suggest you get an md player, nowadays you can get them so small it is amazing
Secondly, I can hardly notice the differance between the different recording modes, and i think that very few can.
Lastly, LP2 is times 2, eg a 90 min disc will then be 180 and LP4 is times 4 for example a 90 min disc will be 360 mins, thats 6 hours and i think that that is amazing for such a tiny thing
hope this was of help to you
